Title: Apparatus for Moulding Patties
Inventor: FELSTEHAUSEN EUGENE FREDRICK
IPC: A21C11/00
Filed: 1967-11-16
Abstract: 1,199,049. Conveyers. FMC CORP. 16 Nov., 1967 [15 Dec., 1966], No. 52108/67. Heading B8A. Also in Divsions [B4-B5] General operation.-Meat patties are moulded by the deposition of material from a hopper 24 into cylindrical cavities 27 carried in a continuously rotated moulding table 26 and from whence they are raised by an upwardly displaceable mould piston 39 at a transfer position displaced 180 degrees from the moulding position. The raised patties are impaled at the transfer position by the fingers of a series of vertically reciprocable blades 66 carried on four pick-up heads 32 provided on a continuously rotated transfer turret 28, whereby each patty is transferred through 180 degrees to a delivery position whereat it is stripped from the blades 66 by the upward displacement of the blades 66 and downward displacement of a stripping grid 70, whereby they fall on to a conveyer 31. Moulding and ejection.-The position of the pistons 39 within the cavities 27 at the moulding station is determined by a stationary horizontal cam track, provided on a vertically adjustable member 46, wherein rides a follower head 49 of each piston 39; the piston 39 is raised to the surface of moulding table 26 at the transfer position by the action of a stationary cam track 52. Transfer turret.-The blades 66 are carried from a rotated hub 69 by a parallelogram linkeage 60, 61 whereby vertical reciprocation of the blades 66, from a lowered position to impale a patty at the transfer position to a raised position on the approach to the patty delivery position and a position displaced 90 therebeyond, is obtained from a stationary cam track 57 in a head 58 whereon rides followers 56 attached to the parallelogram linkage. Each stripping grid 70 is mounted to a collar 71 which rotates with hub 69 and is vertically displaceable with respect thereto, via pins 71a secured to the collar 71 and vertically slidably engaged through the hub 69. The collar 71 is upwardly displaced at 90 degrees intervals, against a spring 72, by a yoke 94 fixed to a lever 95 actuated from a cam 90 by a link 92. The collar 71 is latched in its raised position by a collar locking member 73, a recess 74 whereof engages a pin 75 provided at one end of a bell crank lever 76. Four rollers 78, spaced at 90 degrees intervals around the head 58 including the moulding and transfer positions, successively engage a roller 77 at the other end of bell crank lever 76 to release the locking member 73 whereby the collar 71 and grids 70 descend until the collar 71 is halted by a stop 79. However the grids 70 only perform the effective patty stripping action when the blades 66 are raised at the patty delivery position.

Filed: 1974-12-06
Abstract: 1532407 Calibration of spectrophotometer HYCEL Inc 2 Dec 1975 [6 Dec 1974] 52811/74 Heading G1A In a spectrophotometer with automatic calibration, detectors 96, 98 receive light from a source directly and via a sample holder respectively and a circuit 160 calculates the detector output ratio, which signal is fed to a summing amplifier 172 and added to the output of a programmable voltage source 178 and 186. The sum voltage is amplified in programmable gain amplifier 190 and 200 and the resulting output fed to a measuring device comprising A/D converter 222 and computer 102. In the blank level setting mode, with an empty sample holder, the programmable gain amplifier is set to a predetermined gain and the programmable voltage source is adjusted until the measuring device has a predetermined value, the programmable source value being stored. In the calibration mode, with a reference sample, the stored value is used for the programmable voltage source and the gain of the programmable gain amplifier is varied until the measuring device output has the desired value.

Title: A telephone exchange with an arrangement for automatic fee announcement in direct distance dialling
IPC: H04M3/487
Filed: 1966-11-25
Abstract: 1,130,647. Automatic exchanges. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Nov., 1966 [27 Nov., 1965], No. 52917/66. Heading H4K. A subscriber making a trunk call can dial a code requesting that he be advised of the charge for the call he is about to dial, the advice being given by a talking machine which rings the subscriber back Once he has completed the call and hung up. In the system shown in Fig. 1, a calling subscriber Tln is connected over marker controlled switches TK to a junctor AVS and over switches RgK to a free register Rg. If the subscriber then dials for a trunk call the register connects itself, over junctor AVS and group selector RK to a free outgoing trunk circuit DVS. In response to the charge request digit dialled before the routing digits one of a group of metering pulse counters and associated stores of a device GEE are seized and connected to the junctor AVS over switches RgK, the last stage of which gives the junctor AVS access from its single inlet to both the register Rg and the device GEE. The store of GEE receives the calling number from the identifier JE. Once the connection has been established the counter of GEE receives metering pulses arriving over lead L4. In the device GEE is a talking machine having two registers into which the total number of metering pulses for the call and the calling number are respectively transferred at the end of a call; simultaneous demands on these registers are dealt with one at a time by a lock-out circuit. The subscriber whose number is thus registered is now rung back and a verbal announcement of the charge is made from the talking machine over a connection including lead L5, switches RK, junctor BUS and switches TK. Appropriate spoken numbers and fill-in words to form the announcement are selected from a magnetic tape.

Patent GB-1566756-A (GB)
Title: Load shedding apparatus
IPC: G05D23/20
Filed: 1976-12-23
Abstract: The device comprises, for each phase (R, S, T) whose flow is to be limited to a maximum, a shunt (SH) providing an AC voltage proportional to the AC current in the phase, a peak-detector amplifier (AR, AS, AT) for rectifying this voltage and producing a DC voltage (VR, VS, VT) proportional to the peak value, a photocoupler (PCR; PCS; PCT) for connecting the output of the amplifier to a comparator circuit comprising an operational amplifier (CR, CS, CT), one input of which receives the said DC voltage (VR, VS, VT), and the other a DC reference voltage (UR, US, UT) representing the said maximum current and a voltage divider formed of a diode (D4R, D4S, D4T) and of a resistor (RCR, RCS, RCT). This operational amplifier produces an output voltage (WR, WS, WT) which changes polarity while changing the state of conductivity of the diode when the said DC voltage exceeds the said reference voltage in such a way that the voltage divider emits a control signal on an output circuit (LR, LS, LT) in order to act on means of adjustment which respond to the output signal by decreasing the flow of the current. This device can be used in an electrical heating installation. <IMAGE>

As shown in Fig. 1, a calorifier 3 having a heating coil 26 controlled by a thermostat 27 is a hot water supply and a valve 15 included in the return line 10B of a recirculation system for showers 2 is actuated by an integral temperature control device to divert a portion of recirculated water via line 16 to the calorifier if the recirculated water falls below a desired temperature. An outlet portion 12 of the blending valve 4 contains a thermostat and in a modification (Fig. 3, not shown) line 10B flows directly into portion 12. In the embodiment shown in Fig. 4 a calorifier unit 28 (see also Figs. 5, 6, not shown) has a blending valve mounted on a removable lid and discharging into the water space through outlet 9 in thermostat section 12. Hot water is fed to the valve 4 from a calorifier 3 as before and also feeds a heating coil 33 in the calorifier 28 which is controlled by a temperature limiting outlet valve 32. The recirculation circuit 10A, 10B is connected to the water space of the calorifier 28. In a modification (Fig. 7, not shown) a temperature sensing device for the water in calorifier 28 controls a diverting valve at the inlet to heating coil 33. The arrangement shown in Fig. 8 shows a calorifier 3 and a blending valve 4 as before. A temperature controlled diverting valve 15 diverts return water through a heat exchanger 43 heated by water from the calorifier. Lines 34 are provided for hot water draw-off and central heating circuits.
